Summary

Static routes specify over which interface and gateway a certain host or network can be reached. This chapter is an overview of the Static Routes page in {{{name}}} gateways.

The information in this page is updated in accordance with the TRB1400_R_00.01.05 firmware version.

Static routes

To find information on static route configuration, refer to the figure and table below:

Networking trb manual static routes v1.png


FieldValueDescription
Interfacemobile | lan | default: mobileThe zone where the target network resides
Target*IPv4; default: 0.0.0.0The address of the destination network
Netmask*netmask; default: 255.255.255.255A Mask that is applied to the Target to determine to what actual IP addresses the routing rule applies
GatewayIP; default: noneDefines where the router should send all the traffic that applies to the rule
Metricinteger; default: 0The metric value is used as a sorting measure. If a packet about to be routed fits two rules, the one with the lower metric is applied.
MTUinteger [64..9000]; default: 1500Sets the maximum transmission unit (MTU) size. It is the largest size of a protocol data unit (PDU) that can be transmitted in a single network layer transaction.
Route Typeunicast | local | broadcast | multicast | unreachable | prohibit | backhole | anycast | -- custom -- ; default: unicastSelects route type. Each type specifies a different behavior for the route:
  • unicast -
  • local - routes of this type are added to the 'local' routing table and used only for locally hosted IPs.
  • broadcast - routes of this type are added to the 'local' routing table and used by link layer devices that support the broadcast address principle.
  • multicast -
  • unreachable -
  • prohibit - used to prohibit traffic to specified host or network. When a destination is prohibited, the kernel sends a 'Network is unreachable' response the source address.
  • blackhole - packets that match this type of route are discarded without any response.
  • anycast -
  • -- custom -- -


*Additional notes on Target & Netmask:

You can define a rule that applies to a single IP like this:

  • Target: some IP
  • Netmask: 255.255.255.255

Furthermore, you can define a rules that apply to a range of IPs. Refer to the table below for examples.
